Hi everyone,

I´ve developing a website that works perfeclty. One of the portlets I developed showed dynamic data list results correctly.

Then I added staging funcionality to my website, and now I can´t add records to the dynamics data lists. When I select a DDL I can click on the blue square button to add new data. But then I see everything white without the suitables field (name, title,author, etc.)

The log shows this:
